Private _id As String 
Private _services As New List(Of Service)

     Return _name 
    End Get 
    Set(value As String) 
     _name = value 
    End Set 
End Property 
Property ID As String 
    Get 
     Return _id 
    End Get 
    Set(value As String) 
     _id = value 
    End Set 
End Property 
Public ReadOnly Property Services As List(Of Service) 
    Get 
     Return _services 
    End Get 
End Property 
ReadOnly Property TotalServices As Integer

      s.Add(1) 
      bool = True 
      Exit For 
     End If 
    Next 
    If Not bool Then 
firstThrough: 
     Dim newSer As New Service 
     newSer.Name = sName 
     newSer.Code = sCode 
     newSer.Count = 1 
     _services.Add(newSer)

End Sub 
End Class

你到目前为止尝试过的所有东西？你有没有试过返回“_services.Count”而不是“Services.Count”？ – Andarta

设计师没有改变，但感谢您指出了这一点！进行编辑。我将它添加为仅用于DataGridView的属性，否则我一直在调用Patient.Services.Count – aitchpat

Off-Topic，但强烈建议：避免使用“GoTo”语句。 –

原来，清理和重建解决方案解决了我的问题！将来会更频繁地采取这些措施。
